2 Claims.

This invention relates to glass base guards, and has special reference to metallic guards adapted and designed to be attached to the bases of beverage glasses and the like in order to guard the peripheral and marginal portions of the bases and to prevent said portions from being broken or damaged by the ordinary col-' lisions and contacts to which said portions are subjected in use.

An object of the invention is to provide an improved resilient guard made from a strip of resilient material shaped to form a split annulus or spiral having inwardly diverging wall portions providing a groove or channel adapted to receive the marginal or peripheral portion of a glass base, the device maintaining engagement and connection with the glass base by the resiliency of said device.

Other objects and advantages of the invention will be apparent from the following description, reference being made to the annexed drawing, in which Fig. 1 is a side elevation of the device mounted on and in connection with the base of a beverage glass of conventional construction. 7

Fig. 2 is a sectional View of the device in connection with the base of a beverage glass.

Fig. 3 is a bottom plan View of the device in connection with the base of a beverage glass.

- Fig. 4 is a plan view of the device showing the preferred form thereof before said device is mounted on the base of the glass for which it is intended.

The base I is of conventional construction and form as is the beverage glass 2 with which it is connected and which is supported thereby. The base I is approximately circular and the marginal or peripheral portion 3 thereof includes a flat bottom wall 4 and a downwardly and outwardly inclined top wall 5. The present invention is designed and adapted to be applied and attached to the marginal portion 3 to guard and protect the same from damage and injury resulting from collisions and contacts incident to the handling of the glass.

The device of the present invention is approximately annular or spiral in form and is made by shaping a strip of resilient metallic material to form a, split bottom wall 6 and an inwardly and upwardly diverging top wall I integrally united with the bottom wall 6 along the outer peripheral portions of said walls. The inwardly and upwardly divergence of the wall I from the wall 6 provides a groove or channel 8 designed and adapted to receive the marginal portion 3 of the base I of the glass to which the device is applied. As shown'in Fig. 4 of the drawing, the device is approximately spiral when unattached to a glass base for which it is intended and comprises end portions 9 offset from the planes of the walls 6 and I distances approximately equal to the thickness of said walls 6 and I in order to overlap the opposite end portions II) of the walls 6 and I. The bends II connecting the'ofiset portions 9 with the walls 6 and 7 may be gradual or abrupt, as desired.

A purpose of providing these offset portions in connection with one end of the resilient annulus or spiral is to adapt the device for application to bases I of different sizes and diameters and still maintain an overlapping relationship of the ends in all such applications of the device. When applied to a glass base of the smallest size and diameter to which the device is intended to be applied, the ends 9 and ID will overlap to a greater extent than when the device is applied to any of the larger sizes of bases for which the device is intended.

When the device is applied to the base I, the marginal portion 3 of said base extends into the groove or channel 8, the wall 6 extending inwardly against the lower wall 4 of the marginal portion 3 and the wall I seating against the upwardly inclined wall 5 of the marginal portion 3 of the base and maintaining close contact therewith, so that foreign substances and materials cannot pass between said walls and the base I.

The device may be easily applied to any base I for which it is intended in the following described manner. Place an inverted goblet upon a table, grasp the annulus or guard in the right hand, place the annulus or guard above the goblet base and seat the marginal portion 3 of the goblet snugly within the V-groove or channel 8 of the part of the annulus projecting towards the goblet base, then, while holding the annulus with the bottom of its V-groo-ve or channel 8 closely in contact with the marginal portion 3 of the goblet, turn the annulus around the marginal portion 3 with a right-handed screwing motion. Usually, after approximately half 'a circumferential turn of the annulus about the base, the natural resilience of the metal of which the annulus is composed causes it to snap into place without further turning. Thereupon, the device is released and the inherent resliency thereof closes the annulus'upon and about the marginal portion 3, holding the walls 6 and I in close engagement and contact with the walls IO in close overlapping relationship. When the 7 device is in connection with the base of the glass, the marginal portion 3 of thebase is guarded and protected, so that said marginal portion 3 will not be dented or damaged by the ordinary I .collisions'and contacts to which it is subjected in ordinary uses.

The device is easily removable and replaceable V 'andmay be manufactured and sold at permissible 'costf We do not restrict ourselves unessentially, 'but what we claim and desire to secure by Letters Patent is:

1. A goblet-base protector comprising a sin-. gle-turn; low-pitch, resilient sheet-metal spiral having an inside substantially V- shape groove 2,046,390 4 and 5 of the base and holding the ends 9 and or recess for embracing thetop, the bottom and the edge of'the goblet base near its circumference.

2. A goblet-baseprotector comprising a singleturn, low-pitch; resilient sheet-metal spiral having an inside substantiallyV-shape groove for embracing the circumferential portion of the" base of a goblet, one end of the spiral having a. circumferentially ofiset projection to bridge the MARION L.
